Quite frankly even if it is a fetish they might not have chosen to become that way. You dont go up to a porn site and go tentacle hentai is my thing and forever i will love people getting screwed by tentacles.

So what if a child is consenting and likes it? What if the adult and child grow up and actually have a meaningful relationship? IT could happen you know? Would it be any different for you then to look upon it? Who are we to tell that they cant have a relationship? As parents? Maybe...but you can relate that to people seperating you from your friend...

Now if you want to talk beastality that is just pure sex, zoophilla is the love someone feels about another species and i dont think its too far-fetched too. But i wont get into that.

In any case for me, if its not "natural" to you doesnt mean its not natural at all, so i just accept that some people do that and as long as no one is hurt i dont care. Pedophilla in and of itself is not harmful, just those that force it upon children(and if children want it then would it still be forcing? I wouldnt think so).
